I mean, yes, that was my instinctive response based on just the title. It's always the MTU. But in this case the packet that's being lost is a pure ACK.

- fanf2 3y agoLooks to me like the TLS client hello is being lost, which is why the server is sending duplicate SYN+ACKs.
- jsnell 3y agoNo. To repeat: the client is sending a pure ACK with no data. You can see that packet with a 0 byte payload length in the screenshot. That packet is also getting lost; if it weren't getting lost, we'd be receiving a SYNACK.
